initial release of new RasterFont without color support

Browse Source 
this new design will once create a texture for all chars.
while rendering a string, a list of polygons (position on screen + texture)
for this string is generated on the fly and print at once by glDrawArrays.
atm, there is no support for colors, so everything will display white.
